OpenAI stock has fallen out of favor in the secondary market, with investors quickly turning to its biggest competitor, Anthropic. Ken Smythe, founder of Next Round Capital, said demand for OpenAI stock on his secondary market platform is declining. In the past few weeks, about six institutional investors with significant stakes, including hedge funds and venture capital firms, contacted his firm seeking to sell approximately $600 million worth of OpenAI stock. Last year, these shares would have been snapped up within days, but now there's no interest. Smythe stated, "Buyers are saying they're ready to invest about $2 billion in Anthropic stock." Record demand for Anthropic is also appearing on other platforms, including Augment and Hiive. Augment co-founder Adam Crawley pointed out that OpenAI is valued at $852 billion, while Anthropic is valued at $380 billion, with investors rushing to buy Anthropic stock in hopes of a valuation increase.
